I have assigned angles to three currents, but I am getting an error because Smath thinks the units are different, but they are the same.
Error message is: 'Units don't match'.
Also |I.V current| is displayed as 752/25A instead of 30.08A, guess i need to do some tweaking somewhere.
I suspect I am doing something basically wrong. Hope someone can put me back on track,

kind regards,

John

You simply went wrong to enter the complex exponential function. See that it is blue: it has been inserted as a unit of measurement and then elements are added with different units.

Hello John,
Once all e^ doctored exp(,) ... no more units don't match
At this point, you are the expert to sanity your project.

Thank you Jean for your time correcting my file, unfortunately I could not open it. However, it did give me impetus to carry on with my Pompelmo corrected file.

So here it is so far.

Jean if you would like me to add to this, perhaps draw rotating graphs of the pos, neg zero sequence components i would be happy to, but will need some help with the graph stuff and animation,

Kind regards

John

Its going to be a hot one, 36C today.

You can conserve units [silent] and recover at the end.
First time, can't open... Jean.

Your file has a non calculated matrix you have mentioned.
Here it is corrected, just put a line before expression.
The line usually fix that kind of problems.

And e^ is working fine, no difference in your file while using e^ or exp().

Never ever use "silence units", whatever that garbage term means. It is utterly useless crap.
You would just define again already defined unit with a different name which won't interact with other units.
If available always use bundled, included units. That is what a sane people do.

And Jean, stop misleading new users with your nonsense.

Jean fortunately it works now after a few changes. Please see the R1 version.

Later I will add vectors in a diagram using some info from one of your plots . Then I will add animation, which should make clear to interested parties how + - and 0 sequence works.

kind regards again,

John

Something like this, that you can scale individually.
Cheers ... Jean... please report if can't open.

He didn't "doctored" anything for me.
(Doctored means corrected in Jean's twisted mind, what a stupid word).
There is a bug which (-1)^x sometimes wrong.
He first claimed there is no bug such as that.
I proved there is a bug indeed.
He than claimed (-1)^x don't have a mathematical meaning.
When again proved he is wrong, he posted some useless examples trying to go around the bug.
When I insisted he is still wrong, he simply deleted everything he posted.
e^(π*i) = -1 and there is no difference with e^x and exp(x).

Jean, I have added your graph feature to the document, but cannot quite get it to work.

I need to be able to add magnitude and angle to each of the three vectors with arrow heads and the graph needs to scale as well, perhaps 1.5 times greatest magnitude.
